If not current flows through the galvanometer the find the value of unknown resistance X. Assume that resistance per unit length of wire AB is 0.2 `Omega//cm`.
then also calculate total current given by battery.

Total current flowing from the battery is 1A. Find the total resistance of the circuit:

When the current flowing in a galvanometer is (1/n) of the total current, the resistance of the shunt will be

Calculate the current flows through resistance 2Omega .

Calculate the current flows through resistance 2Omega .

Calculate the current flows through resistance 2Omega .

In an ammeter, 4% of the total current is passing through the galvanomter. If the shunt resistance is 5 Omega , then the resistance is Omega , then the resistance of the galvanometer will be

A battery of unknown emf and internal resistance is given to a student for the experiment. When student connects the battery to an external resistance of 10 Omega then 1A current flows through the circuit and when the same is connected to 15 Omega resistance then 0.75 A current flows through the circuit . Calculate the emf and internal resistance of the given battery.
